textractor.__version__
-----
'1.7.4'

from platform import python_version
print(python_version())
-----

```

## Reproduction

```
import os
import pathlib
from textractor import Textractor
from textractor.data.constants import TextractFeatures
import textractor

textractor.__version__

from platform import python_version
print(python_version())

DATA_DIR=pathlib.Path.home().joinpath("home/repository/data/ml/medical_report/pdf")
FILEPATH=DATA_DIR.joinpath("MedicalExaminerReportExample_13.pdf")

extractor = Textractor(profile_name="eml-ap-southeast-2")
document = extractor.analyze_document(
file_source=str(FILEPATH),
features=[
TextractFeatures.LAYOUT,
TextractFeatures.FORMS,

## PDF

* [MedicalExaminerReportExample_13.pdf](https://github.com/aws-samples/amazon-textract-textractor/files/14457466/MedicalExaminerReportExample_13.pdf)

Reproduce the behavior with MedicalExaminerReportExample_13.pdf using the shown Textractor.analyze_document call and the TABLES and LAYOUT features. Inspect document.tables[0].title and compare its text with the table visualization; done means the text field above the table is not reported as the table title while the actual table title remains available.
